T0 LZZ whom it' may concern.-

Be it known that I, ABIATHAR BISHOP, a resident of Pittsburg, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Pile-Drivers, and I dofhereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to pile-drivers, and has for its object to providea cheap and simple device of this character whereby the same can be usedas a pile-driver, derrick, or traveling crane, as well as one in whichwire rope can be used in connection with the ram; and a further obj ectis to provide such a device which will allow the trucks to be liftedfrom the track and be turned at right angles thereto.

A still further object of the device is to have such an operation oftheparts which will relieve the strain on the rope used when the ram isstriking, and one 1n which the feeding parts will not turn back whenpower is taken off, thereby dispensing with the use of braking means.

My invention consists, generally stated, in the novel arrangement,construction, and combination of parts, as hereinafter more specificallyset forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains toconstruct and use my improved pile-driver, I will describe the same morefully, referring to the accompanying drawings, in which Figure 1 is aside elevation of my improved pile-driver. Fig. 2 is a top plan view ofthe pile-driver with the supporting-beams broken away or removed. Fig. 3is a bottom plan view with the track and other parts removed. Fig. 4 isan enlarged detail view showing one of the jacking devices andconnections to the samefor operating. Fig. 5 is an enlarged detail viewof the apparatus forming the truck. Fig. 6 is an enlarged detail view ofa portion of the jack-operating mechanism. Fig. 7 is an enlarged detailview of the spring-actuated sleeve.

Like symbols of reference herein indicate like parts 'in each of thefigures of the drawings.

zIls illustrated in said drawings, 1 represents the truck-body, which issupported on the axles 2, and on these axles are mounted the wheels 3for traveling lon the rails 4 of a suitable track. On the bed 5 ofthetruck 1 is mounted a circular track 5, on which the wheels or rollers 6are adapted to travel, and these rollers 6 are mounted and carried byarotatable platform 7, which is mounted above said truck 1 and issupported by and is rotatable on said track 5 through the medium of saidrollers 6. A shaft 8 (shown in dotted lines, Fig. 1) passes through saidplatform 7, and on its upper end is provided the bevelpinion 9, whileits lower end is provided with the bevel-pinion 10, which is adapted tomesh with a bevel-pinion 11, mounted on a shaft 12, extending acrosssaid axles 2, and

this shaft 12 is provided with the worms 13 at each end thereof forengaging with a worm-gear 14, mounted on each of said axles. Thebevel-pinion 9 is adapted to mesh with a bevel-pinion 15, mounted on ashaft 16, which shaft extends across said platform 7 in a parallel linewith the rope-drums hereinafter described, and is j ournaled in thebearings 7, carried by said platform. A gear-wheel 17 is mounted on saidshaft 16, which is adapted to mesh with a gear-wheel 18, mounted on thedrum-shaft 19, Awhich carries the drum 20, and this gear-wheel 18 mesheswith another gear-wheel 21, mounted on the drum-shaft 22, carrying adrum 23. These drums 20 and 23 are connected to the engine 24 in theusual manner through the drive-shaft 24', such engine being operatedthrough the boiler 24 and all these parts being mounted on the platform7, while the shafts 19 and 22 for said drums are j ournaled in theframes or bearing-plates 25, and such frames have also journaled thereinthe shaft 26, carrying the reversible swinging gear device 27. rlhereversible swinging gear device 27 is of a well-known construction andis controlled by the lever 28, while being operated through a gear-wheel29, which is mounted on the shaft 26 and meshes with the gear-wheel 21on the drum-shaft 22. A gear-wheel 30 is mounted on a cross-shaft 31,located under the platform 7, and this gear-wheel 30 meshes with thegear-wheel 30 on the shaft 26. rIhe shaft 31 is provided with a worm 32-thereon, and such worm is adapted to be engaged, through the clutchface33, by a clutch 34 on said shaft, which is operated by a lever 35, whilesaid worm 32 is adapted to mesh with a circular worm-rack 36, supportedby the standards 37, extending up from the truck-body 1.

The supporting-beams 38 for carrying the uprights 39 extend under theplatform 7 IOC lgear-wheel 52 and form part of the same, while within Ythese uprights the ram 40 slides within guides 40 by means of the lugsor flanges 40 thereon. These beams carry the rollers 6 for the rotatableplatform 7 and the bearings 31 for the shaft 31,`and such uprights 39are mounted on a detachable portion 38 of said beams 38, which isconnected by bolts 38"l to the permanent portion 38 of said beams.Mounted on the cross-pieces 41 41 between said beam portions 38 and 38are the jacks 42, 42, and 42, and each is provided with a screw-bar 43thereon, which passes through and engages with the cross-pieces 41 41and has a head 44 at the lower end thereof. Mounted on each of thescrew-bars 43 is a worm-wheel 45, and such wheel for-the` jack 42 isadapted to engage with a worm46,mounted on a cross-shaft 47 supported inbearings 47 extending out from the cross-piece 41.

pinion 48 is mounted on the end of this shaft 47, which meshes with alike pinion 49 and shaft 50, extending along one of the detachable beamportions 38 and supported in bearings 51, extending out therefrom. Agearwheel 52 is mounted on this shaft 50 and is provided with a clutchface 524 thereon, which is adapted to be engaged by a clutch 53 on saidshaft 50 and operated by the lever 53 while such gear-wheel 52 mesheswith a on a shaft 50', extending along and supported by bearings 51 fromthe permanent beam portion 38. A pinion 51 is mounted on said shaft 50which meshes with a like pinion 52a, mounted on the crossshaft 31 underthe platform 7, and another pinion 53 is mounted on said shaft 50',which is adapted to mesh with a pinion 53a, mounted on a cross-shaft 54,which extends along the cross-piece 41 in suitable bearings and providedwith a worm 54 which engages with the worm-wheel 45 on the jack 42,while a worm 55 on said shaft 50 meshes with the worm-wheel 45 on thejack 42. A clutch 56 is mounted on the shaft 50 and is adapted to engagewith clutch-faces 55 and 55 on said pinion 53 and worm 55, respectively,which clutch 56 is operated by the lever 56.

Extending up from each side of the platform 7 are the posts or standards57 which are supported by the rods 58, connecting the upper ends of saidposts and the said platform, While supporting-rods59 connect the upperends of posts 57 with the upper ends of the uprights 39. The rope 60,which is preferably' formed of wire, is connected at one end of the topof the ra-m 40 and asses over a. shcave 61, mounted on a shaft 61 andjournaled in bearings 61 at the top of said uprights 39, while such ropealso passes around a spring-operated sheave 62 on the detachable portion38 of the supporting-beams 38l and is connected at its opposite end toand is wound around the drum 23. This spring-operated sheave 62 has itsbearings 62 mounted on the end of a rod 62, which extends through aframe 63, easily journaled around a cross-bar 63, extending across andbetween the detachable beam portions 38 by a sleeve 63, while a spiralspring 64 fits around said rod 62" and is confined between a collar orflange 64 on the end of said rod and a plate 64 on the end of said frame63. A boom 65 is pivoted at -65 in bearings 65" on the permanentportions 38 of said supporting-beams 38 and extends up at an angle orincline to and is connected around the shaft 61 at the upper end of theuprights 39, such boom acting as the ordinary ladder for the uprights 39of the driver and being supported by the rods 66, which are connected tosaid boom at 66 and to the upper end of said posts 57 and-cross-piece41, as at 66. The device used in operating the boom 65 is shown bydotted lines in Fig. 1, and consists of rope 67, which passes from thedrum 2O over and around a sheave 67,

'mounted on a shaft 67, journaled in said posts 57, andaround a sheave68, such sheave 68 being mounted on a shaft 68 journaled in the ends ofthe bars 68, and said bars being loosely hung or suspended from saidshaft 61.

The use and operation of my improved pile-driver are as follows: Thetruck 1, carrying the platform 7, is adapted to move along the rails 4through the medium of the engine 24, operating the gear-wheels 18 and 21on the drumshafts 19 vand 22, respectively, from the drive-shaft 2 4inthe usual manner, which, through the gear-wheel 30 on the reversiblegear-shaft 26 being engaged by said gear-wheel 21, will act to operatesaid shaft 26 and revolve the gear-wheel 29 on said shaft, sothat suchgear-wheel 29, meshing with the gear-wheel 3,0 on the shaft 31, will actto operate said shaft 31. As the shaft 31. is thus turned' the clutch 34thereon being thrown into the face 33 on the worm 32 will act to engagesaid worm with the circular worm-rack 36, so that the platform 7,carrying the working parts, can be revolved or swung on the truc i 1 tothe position desired by the rollers 6 on said platform traveling aroundon the circular track 5 on said truck,

and the reversible gear device 27 on the shaft 26 will permit theswinging of the driver in any position of the platform 7 through thelever 28 and while the engine 24 is going ahead and in turning thegear-wheel 30 continuously in the one direction. Vhenit is desired tomove the truck 1 along the rails 4, the engine 24 is operated to drivethe drumshaft 19 in the usual manner from the driveshaft 24 and byreason of the gear-wheel 18 on said shaft 19 meshing with the gear-wheel17 on the cross-shaft 16 the said shaft 16 will be revolved, and with itthe pinion 15 thereon, which pinion 15 meshing with the pinion 9 on theupright shaft 8 will act to re- IOO ITO

volve said shaft 8 and with it the pinion 10 at the lower end of saidshaft 8. As the pinion 8 meshes with the pinion 11 on the shaft 12 thisshaft 12 will also be revolved and will rotate the worms 13 at each endof said shaft, which worms, meshing or engaging with the worm-wheels 14,mounted on the axles 2 of the truck 1, will act to turn said axles, andwith them the wheels 3. The truck 1, carrying the platform 7 and workingparts, can be moved along the rails 4 through said wheels 3 in eitherdirection by operating such parts while the engine 24 is going ahead andrevolving said parts in the desired direction through the gearing andmech ism connecting the drum and shaft 191as in the ordinary manner.When it is desired to raise the platform 7 of the device, and with itthe truck 1, for the purpose of swinging said truck at right angles, soas to be placed upon and travel on rails laid at right angles to therails 4, all that is necessary is to lower the jacks 42, 42', and 42"down onto the groundlfevel or down upon blocks placed on the V"groundunder said jacks, and this can be accomplished when the clutch 34 on theshaft 31 is out of engagement with the face 33 on the wormv 32 bythrowing the clutch 53 on the shaft 50 into engagement with theclutchface 52 on the gear-wheel 52. After this is done and by reason ofthe shaft 31 being continuously revolved while the engine 24 isoperating in going ahead, the pinion 51a of said shaft 31, meshing withthe pinion 51" on the shaft 50', will act to revolve said shaft 50', andwith it the gear-wheel 52" on the end of A` said shaft 50', so that thegear-wheel 52 being in mesh with thegear-wheel 52 on said shaft 50 willrevolve said shaft 50 when said shaft 52 is engaged by said clutch 53through its lever 53', and the pinion 49 on said shaft 50 being in meshwith the pinion 48 on the shaft 47 will act to turn said shaft 47, andwith it the worm 46 thereon. As the worm 46 is in engagement with theworm-wheel 45,

the said wheel 45 will be turned, and with itl the screw-bar 43 of thejack 42, so that said jack will be lowered down to allow its head 44 tocome against the ground or block, and such lowering being continuedsufficiently will act to raise the outer end of the supporting-beams 38and one end of the truck 1 from the rails 4. The clutch 53 can now bethrown out of engagement with the face 52 on the gear-wheel 52 and theclutch 56 thrown into engagement with the face 55" on the worin 55through the lever 56', which will cause said worm to turn theworin-wheel 45 on the jack 42', with which it engages, as Vwell as thescrew-bar 43 on said jack 42', thereby lowering said jack 42 down ontothe ground or block. and raising one side of the inner end of the beams38 and truck l, as before described. After this is accomplished 6 5 theclutch 56 is thrown out of engagement with the face 55" on the worin 55and into engagement with the face 55 on the pinion 53" through the lever56, which will cause the turning of the cross-shaft 54 by reason of thepinion 53L on said shaft 54, and this will allow the worm 54 on saidshaft 54 to turn the worm-wheel 45 on the jack 42" with which it engagesand also the screw-bar 43 on said jack 42, thereby lowering said jack 42down onto the ground or block and raising the other side of the innerends of the beams 38 and truck 1, as before described. As both ends ofthe beams 38 and truck 1 are thus raised to a sufficient height and thewheels 3 are freed from the rails 4 the said truck can be turned on theplatform 7 by throwing the clutch 34 on the shaft 31 into engagementwith the worm 32, which, through the worin-wheel 36 being operated bysaid worm from said shaft, will allow the rollers 6 to travel around acircular track 5, so that the truck can be lowered with the platform 7by reversing the operations of raising the jacks, as before described,while the engine 24 is going ahead through the reversing-gear device 27and such truck placed upon a track running at right angles to the rails4. During the dropping of the ram 4() within the uprights 39 by the wirerope 60, which leads from the drum 23, operated from the engine 24, thestrain on said rope in striking will be overcome while it passes aroundthe sheaves 61 and 62 by reason of the spring 64 within the'frame 63 andaround the rod 62, being compressed. between the flanges 64 and 64 onthe rod 62 and frame 63, respectively, which rod 62" carries thebearings 62 for said sheaves 62.

n case it is desired to use the device as a derrick, hoist, or travelingcrane, &c., the detachable beam portions 38 can be separated from thepermanent portion 38 of the supporting-beams 38 by unscrewing the bolts38a, connecting these parts together, and then detaching the uprights 39from the bearings 61, as well as the rods 59 from said uprights and fromsaid posts 57 and the rods 66 from said posts, boom 65, and portions 38,so that said portions 38, uprights 39, rods 59 and 66 can be removedfrom the device. In this case the ram 40 and spring-operated sheave 62can also be removed, and the rope 60 around the sheave 61 and drum 23can be attached to a bucket, scraper, &c., which will allow the boom 65to move freely upon its pivotal point in bearings 65', so that such boomcan be raised and lowered on such pivoted bearing from the drum 20 bythe engine 24 through the medium of the rope 67, leading from said drumand passing around the sheaves 67 on the posts 57 and the sheaves 68,suspended from the shaft 61 on the outer end of said boom and carryingthe sheaves 61 for use in the operation of devices in connection withsaid boom.

It will be evident that the pendulum leads on what are known asmonkey-drivers can be attached at the top of the boom in .place of theuprights, so that the device can be used for the placing and driving ofpiles at an angle in the building of railroad and other liketrestle-work. It will also be evident that in work necessitating the useof the driver upon water the I-beams or channelbeams can be used inplace of the rails for the wheels of the truck, in which case suchwheels can be moved along on the side of said beams and between theflanges therein, so as to allow the wheels to play between such flangesand have the truck in place when the device is rocked or swayed onaccount of waves, rough water, &c. lt will also be obvious that thespring-operated sheave for the wire rope can be placed at other pointson the device to operate in connection with said rope, and by its usethe strain will be so relieved as to prevent its breaking, as has beenfound with its use in this class of work. It will further be obviousthat by reason of the detachable frame portion the device can be madeportable, so that the jacks can be used to raise the platform andtrucks, in order that wheels for moving the device from place to placeby the engine can be placed upon the axles of said trucks.

Various other modifications and changes in the construction, design, anduse of the various parts of my improved pile-driver may be resorted towithout departing from the spirit of the invention or sacrificing any ofits advantages.

It will thus be seen that in my improved pile-driver the construction iscapable ofa variety of uses and purposesby a simple interchange of partsand the driver can be moved forward and backward easily and quickly forbringing the ram into position for driving the pile, as well as to swingor rotate the platform on the truck, so as to move the ram on eitherside of the truck and around the same, as may be desired. It will alsobe seen that the device can be easily and quickly raised and lowered, sothat the truck can be placed upon different lines of tracks to work andat different positions, all of which points will greatly -facilitate thework of driving piles, hoisting, &c.
